Abstract

PROBLEM TO BE SOLVED: To provide a cap having a blade sharpening function in which a cap covered on a blade of a cutting tool such as a scissors is equipped with a blade sharpening component.SOLUTION: A cap having a blade sharpening function characterized in that a blade sharpening component is provided in a recess of a cap covered on a blade of a cutting too such as a scissors, a knife or the like, and the blade sharpening component has a main body of a hard metal alloy. According to the invention, by bringing an edge of a rod-like blade sharpening component into contact with a blade, a contact area of the blade and the blade sharpening component becomes small and a force can be applied with a good efficiency, whereby the blade can be easily sharpened. Further, since the blade sharpening component does not require a flat area such as a grind stone, said blade sharpening component can be down-sized and can be provided on a relatively small cap.SELECTED DRAWING: Figure 2

Description

本発明は、鋏などの刃物の刃に被嵌するキャップに刃研ぎ部材を備えたものに関する。   The present invention relates to a cap provided with a blade sharpening member on a cap fitted to a blade of a blade such as a scissors.

刃物の刃は使用するにつれて摩損し切れ味が落ちるため、刃を砥石などの研磨具で研ぎ、刃を鋭利にして切れ味をよくする必要がある。例えば、鋏やナイフなどは様々な場所で携帯し使用することがあるために、作業時に切れ味が落ちていることが判明しても研磨具を携帯していなければ、そのまま使用せねばならず作業効率が低下する。その解決する手段の一例として、特許文献１に記載されているナイフを収める鞘に研磨布紙又は砥石片などの研磨部材を取り付けているものがある。   Since the blade of a blade is worn and loses its sharpness as it is used, it is necessary to sharpen the blade with a polishing tool such as a grindstone to improve the sharpness by sharpening the blade. For example, since tools such as scissors and knives may be carried and used in various places, even if it is found that the sharpness is lost during work, it must be used as it is if you do not carry a polishing tool. Efficiency is reduced. As an example of the means for solving the problem, there is one in which a polishing member such as a polishing cloth or a grindstone piece is attached to a sheath containing a knife described in Patent Document 1.

実開昭６０−１２９２７７号公報Japanese Utility Model Publication No. 60-129277

しかしながら、刃物の鞘に砥石や研磨布紙を一体として取り付ける場合、研磨を行うには一定の大きさの平らな面積を有する必要があるために、ナイフのような刃の幅が大きく、鞘も大きいものには適しているが、鋏などの刃が比較的小さいものに被嵌するキャップに刃研ぎ部材を一体として取り付けるのに適していない。   However, when a grindstone or abrasive cloth is attached to the blade sheath as a unit, it is necessary to have a flat area of a certain size for polishing. Although it is suitable for large ones, it is not suitable for attaching a blade sharpening member integrally to a cap that fits on a relatively small blade such as a scissors.

上記の課題に鑑み、本発明では、鋏やナイフなどの刃物の刃に被嵌するキャップの凹所にエッジを有する棒状の刃研ぎ部材を備えたことを特徴とする刃研ぎ付きキャップを提供する。   In view of the above problems, the present invention provides a blade sharpening cap characterized by including a rod-shaped blade sharpening member having an edge in a recess of a cap fitted to a blade of a blade such as a scissors or a knife. .

また、上記の刃研ぎ付きキャップの構成に加え、刃研ぎ部材は超硬合金を主体とするものからなることを特徴とする刃研ぎ付きキャップである。 Further, in addition to the configuration of the above-mentioned cap with blade sharpening, the blade sharpening member is composed of a cemented carbide alloy as a main component.

請求項１記載の発明によれば、エッジを有する棒状の刃研ぎ部材のエッジを刃に当てることで、刃と刃研ぎ部材との接地面が小さくなり力を効率よく加えることができるので、容易に刃を研ぐことができる。また、刃研ぎ部材は砥石のような平らな面積を必要としないため、小型化することができ、比較的小さいキャップなどに備えることができる。   According to the first aspect of the present invention, by touching the edge of the bar-shaped blade sharpening member having an edge to the blade, the ground contact surface between the blade and the blade sharpening member is reduced, and the force can be applied efficiently. You can sharpen the blade. Further, since the blade sharpening member does not require a flat area like a grindstone, it can be miniaturized and can be provided in a relatively small cap or the like.

請求項２記載の発明によれば、刃よりも非常に硬い超硬合金を主体とするものからなる刃研ぎ部材によって少ない力で刃を研ぐことができる。   According to the invention described in claim 2, the blade can be sharpened with a small force by the blade sharpening member mainly composed of a cemented carbide which is much harder than the blade.

本発明の刃研ぎ付きキャップの一例について、図面に基づいて詳細に説明する。   One example of the cap with sharpened edge of the present invention will be described in detail based on the drawings.

本発明において、刃研ぎ付きキャップ１は図１に示すように、鋏３の刃を保護するため、鋏３の刃に被嵌されるものである。キャップ１は鋏３の刃が閉じた状態で装着できるような形状をABS樹脂によって成形され、先端部の凹所４に刃研ぎ部材２が一体となって配置されている。   In the present invention, as shown in FIG. 1, the blade sharpening cap 1 is fitted on the blade of the flange 3 in order to protect the blade of the flange 3. The cap 1 is formed of ABS resin so that the cap 1 can be mounted with the blades closed, and the blade sharpening member 2 is integrally disposed in the recess 4 at the tip.

また、図２において、鋏から離脱させた状態の刃研ぎ付きキャップを詳細に示している。キャップ１の先端部に凹所４を設け、そこに超硬タングステンを主体としたものからなる棒状の刃研ぎ部材２を固定する。この刃研ぎ部材２は凹所から突出しない程度の厚みを有する直方体であり、直方体の面が直角に交差することによってエッジ５が構成される。   FIG. 2 shows the cap with sharpened blade in a state of being detached from the ridge. A recess 4 is provided at the tip of the cap 1, and a rod-shaped blade sharpening member 2 made mainly of tungsten carbide is fixed thereto. The blade sharpening member 2 is a rectangular parallelepiped having a thickness that does not protrude from the recess, and the edge 5 is formed by intersecting the rectangular parallelepiped surfaces at right angles.

このようなキャップ１に刃研ぎ部材２を一体とすることで、鋏などを携帯する際に、別に砥石などの研磨装置を携帯する手間が省け、使用場所において研磨することが可能になる。また、刃研ぎ部材２は凹所４に固定することで、刃研ぎ部材２と刃以外との接触による劣化や破損を抑制することができる。   By integrating the blade sharpening member 2 with such a cap 1, when carrying a scissors or the like, it is possible to save the trouble of carrying a polishing device such as a grindstone separately and to polish at a place of use. Further, by fixing the blade sharpening member 2 to the recess 4, it is possible to suppress deterioration and breakage due to contact between the blade sharpening member 2 and other than the blade.

次に、図３で示すように、刃研ぎ部材２を用いて刃６を研磨する方法を説明する。まず、鋏３を開いた状態にするとともにキャップ１を持ち、刃研ぎ部材２のエッジ５を刃６に接触させる。その後、刃研ぎ部材２を刃に沿った方向（矢印方向A）に接触させたまま適度に往復させて研磨することで、刃６を鋭利にする。   Next, as shown in FIG. 3, a method for polishing the blade 6 using the blade sharpening member 2 will be described. First, the flange 3 is opened, the cap 1 is held, and the edge 5 of the blade sharpening member 2 is brought into contact with the blade 6. Then, the blade 6 is sharpened by polishing the blade sharpening member 2 while reciprocating appropriately while keeping the blade sharpening member 2 in the direction along the blade (arrow direction A).

この刃研ぎ部材２のエッジ５を刃６に当てることで、刃６と刃研ぎ部材２との接地面が小さくなり、研ぐための力を効率よく加えることができる。また、刃６よりも非常に硬い超硬タングステンを主体とするものからなるため、研ぐための力は小さくなる。したがって、少ない力で容易に刃を研磨することができる。さらに、刃研ぎ部材２は砥石のような平らな面積を必要としないため、小型化することができる。   By applying the edge 5 of the blade sharpening member 2 to the blade 6, the ground contact surface between the blade 6 and the blade sharpening member 2 is reduced, and a sharpening force can be efficiently applied. Moreover, since it consists mainly of super hard tungsten harder than the blade 6, the force for sharpening becomes small. Therefore, the blade can be easily polished with a small force. Further, since the blade sharpening member 2 does not require a flat area like a grindstone, it can be miniaturized.

なお、以上の実施形態において、刃研ぎ部材２は刃６よりも十分硬ければよく、超硬タングステンを主体とするものからなるもののみに限らない。また、刃研ぎ部材２には鋭角なエッジ５があればよく、直方体のエッジのみに限らない。さらに、鋏のみに限らず刃に被嵌するキャップにも本発明を適用することができる。   In the embodiment described above, the blade sharpening member 2 only needs to be sufficiently harder than the blade 6, and is not limited to one made mainly of tungsten carbide. The sharpening member 2 only needs to have an acute edge 5 and is not limited to a rectangular parallelepiped edge. Furthermore, the present invention can be applied not only to the collar but also to a cap fitted to the blade.

鋏などのキャップの凹所に刃研ぎ部材を一体として配置することで、刃研ぎ付きキャップを提供することができ、その結果、鋏を携帯する際に邪魔にならず、どこでも刃を研ぐことができ、作業効率を向上させることが可能である。また、その刃研ぎ付きキャップを他の刃物の刃を研ぐために使用することも可能である。   By arranging the blade sharpening member integrally in the recess of the cap such as a scissors, it is possible to provide a cap with a blade sharpening, and as a result, it is possible to sharpen the blade anywhere without being in the way when carrying a scissors It is possible to improve work efficiency. The blade sharpened cap can also be used to sharpen the blades of other blades.
